For example, the detection function transmits a detection signal to the power supply device 40 when the vehicle 30 is detected. If the vehicle can be detected by a power supply coil or the like, the coil may be used for both power supply and detection.

Next, power supply control processing performed by the power supply control system 1 will be described with reference to FIG. 3 . FIG. 3 is a sequence diagram illustrating power supply control processing performed by the power supply control system according to one embodiment.

First, when the power supply control device 20 acquires disaster information, it creates disaster information (step S101). The disaster information created here includes the type and scale of the disaster, and priority setting information regarding the priority of power supply to the vehicle 30 set for the disaster.

The power supply control device 20 distributes the disaster information to the vehicle 30 traveling in the relevant area and the power supply apparatus 40 installed in the area (step S102).

On the other hand, the power supply device 40 determines whether or not disaster information is received (step S103). If the power supply control unit 44 has not received disaster information (step S103: No), it repeats determination of whether or not disaster information has been received. On the other hand, when the power supply control unit 44 determines that disaster information has been received (step S103: Yes), the process proceeds to step S104.

In step S104, the power supply device 40 changes the setting of the upper limit value of power supply for each type of the vehicle 30 according to the priority. Specifically, upper limit value setting unit 43 creates setting information for changing the setting of the upper limit value of charging according to the type of vehicle 30, and outputs the setting information to vehicle 30 to which power is supplied. As a result, in the vehicle 30 , the upper limit value of the remaining power storage amount is changed according to the type of the vehicle 30 .

The power supply device 40 detects the vehicle 30 (step S105). The power supply control unit 44 determines whether or not the wired power supply unit 41 and the vehicle 30 are connected, or whether the vehicle 30 is positioned on the wireless power supply unit 42, thereby allowing the power supply to the power supply device 40. The location of the vehicle 30 is detected. When the power supply control unit 44 determines that the vehicle 30 is not arranged (step S105: No), the process proceeds to step S107. Further, when the power supply control unit 44 determines that the vehicle 30 is arranged (step S105: Yes), the process proceeds to step S106.

In step S<b>106 , the power supply control unit 44 compares the number of power supply possible times set for the connected vehicle 30 and the current number of power supply times. When the power supply control unit 44 determines that the number of times of power supply is equal to or greater than the number of times that power can be supplied (step S106: Yes), the power supply control unit 44 proceeds to step S108 and does not perform power supply processing to the vehicle 30 concerned. On the other hand, when the power supply control unit 44 determines that the number of times of power supply is less than the number of times that power can be supplied (step S106: No), the process proceeds to step S107.

In step S<b>107 , the power supply device 40 supplies power to the vehicle 30 . At this time, the power supply control unit 44 controls the power supply via the connection unit (the wired power supply unit 41 or the wireless power supply unit 42 ) connected to the vehicle 30 . For example, the power supply control unit 44 acquires the remaining power storage amount from the vehicle 30 or reads the voltage value, and supplies power until the remaining power storage amount reaches the upper limit value. At this time, the upper limit value of the power supply differs depending on the type of the vehicle 30, and the lower the priority of the vehicle 30, the higher the upper limit value.

After the power supply process, the power supply control unit 44 determines whether or not to cancel the priority setting for power supply to the vehicle 30 (step S108). When the power supply control unit 44 obtains the follow-up report of the disaster information, etc., and determines that the disaster response is not canceled and the priority setting is not canceled (step S108: No), the process returns to step S105. Repeat the subsequent steps. On the other hand, if the power supply control unit 44 determines that the disaster response has been canceled and the priority setting is to be canceled (step S108: Yes), the process proceeds to step S109.

In step S<b>109 , the power supply control unit 44 returns the setting of the upper limit value of the remaining power amount according to the priority to the normal state. For example, the power supply control unit 44 restores the upper limit value of the SOC set in each vehicle 30 to the upper limit value of the normal state.
After that, when receiving new disaster information, the power supply control device 20 performs the disaster information creation process in step S101 again. The power supply device 40 changes the upper limit value and performs power supply processing according to the new disaster information.

It should be noted that the process of step S105 is preferably performed periodically. The shorter the processing interval, the better, in order to cancel the priority setting in near real time. Further, when the power supply device 40 does not receive disaster information, the power supply device 40 supplies power to the connected vehicle 30 at the upper limit value of the normal state regardless of the type.

Here, when the priority is set by the disaster information and the upper limit value is changed, the priority setting information is distributed to the vehicle 30 traveling in the disaster area, and the power supply priority is displayed on the vehicle 30. good too. FIG. 4 is a diagram illustrating an example of an image displayed on a display provided in a vehicle according to one embodiment; In the display image W1 shown in FIG. 4, the priority setting information D2 is superimposed on the navigation image D1 including map information and the like. The priority setting information D2 includes information indicating that the current location where the vehicle is traveling is within the disaster area, and the priority class of the vehicle 30 itself. These displays inform the driver of the vehicle 30 traveling in the disaster area that the vehicle is traveling in the disaster area and the priority of power supply. The driver can confirm the priority and the current SOC, and can travel in consideration of the place and timing to supply power.

In the present embodiment described above, in the event of a disaster, the priority of power supply is set for each type of vehicle 30, and the upper limit of the remaining amount of power storage is increased for vehicles with low priority. In the present embodiment, priority is given to supplying power to a vehicle with a high priority to maintain running of the vehicle, and the remaining amount of power storage when the vehicle with a high priority is fully charged is increased. According to the present embodiment, when power supply priority is given to each type of vehicle, even a vehicle with a low priority can be maintained in a drivable state for a long time.

Although the power supply device 40 including the wired power supply unit 41 and the wireless power supply unit 42 has been described as an example in the embodiment, the present invention can also be applied to a power supply device including only one of them.

In addition, in the present embodiment, an example in which the power supply device 40 controls power supply with reception of disaster information as a trigger has been described, but not limited to disaster information, for example, a system of a base station that supplies power to the power supply device 40 Even when the power supplied by the power supply device 40 is unstable due to a failure or the like, power supply control that sets the priority and the upper limit value can be applied.

Further, in the present embodiment, an example has been described in which the storage unit 23 of the power supply control device 20 stores information about priority, and the disaster information distributed from the power supply control device 20 includes information on the priority. The storage unit of the power supply device 40 may store priority information, and each power supply device 40 may set the priority and change the upper limit according to the type of disaster. At this time, the power supply control device 20 outputs disaster information that does not include priority to the power supply device 40 .
Furthermore, on the power supply control device 20 side, an upper limit value corresponding to the priority may be set, and the set setting information may be output to the vehicle 30 . In this configuration, the power supply control device 20 functions as an information creating device (first and second devices).
